Black Children Tend to be Diagnosed with Autism Later than White Children

The rate of diagnosis for autism spectrum disorders (ASD) is the same among all racial groups - one in 110, according to current estimates. However, a study by a Florida State University researcher has found that African-American children tend to be diagnosed later than white children, which results in a longer and more intensive intervention.

The reasons for later diagnoses include a lack of access to quality, affordable, culturally competent health care, according to Martell Teasley, an associate professor in Florida State's College of Social Work who has conducted a comprehensive review of researchliterature on autism and African-American children. In addition, the stigmaattached to mental health conditions within the black community contribute to misdiagnoses of autism, and underuse of available treatment services.

"There are no subjective criteria for diagnosing autism. Only brain scans can truly provide appropriate diagnoses, because we are dealing with biological and chemical imbalances in the brain," Teasley said. "Not every child is going to have access to this kind of medical evaluation, particularly those who are indigent and don't have health care funding."

Teasley examined ASD diagnosis and treatment strategies, and their effect on African-American families, in "Autism and the African-American Community," a paper published in a special issue of the journal Social Work in Public Health (Vol. 26, Issue 4, 2011) that dealt with health-care policy issues in the black community related to the human genome. Teasley co-wrote the paper with Ruby Gourdine, a professor of social work at Howard University in Washington, D.C., and Tiffany Baffour, an associate professor of social work at Winston-Salem State University in North Carolina.

Because of the social stigma, Teasley says that some African-American families might be resistant to accept a diagnosis and treatment.

Autism is a complex lifelong neurodevelopmental disorder usually identified by age three. A child with autism will show different behaviors than typical developing children. Parents become concerned that their child may lack eye contact, be deaf, is not yet talking, resists cuddling, appears aloof and avoids interacting with others.

These behaviors may begin shortly after birth or develop as a child grows older.

Symptoms will range from mild to severe. Mental retardation is commonly associated in autism. The Centers for Disease Control in Atlanta and others report black children have significantly higher rates of mild mental retardation than white children do and socioeconomic factors cannot explain the differences.
